LAND-GRADER.

To all whom 'it may concern Be it known that I, CHARLES H. GUNN, a citizen of the United States, residing at Modesto, in the county of Stanislaus and State of California, have invented certain new and useful Improvements in Land- Graders; and I do declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this application.

T his invention relates to improvements in dirt handling apparatus and particularly to land graders the object of the invention being to provide a light and easily handled grader which will be much more easily handled than an ordinary scraper and one which will be exceedingly easy 011 the stock used to pull the same. I further aim to produce a grader in which the depth of the out can be very nicely adjusted and also one in which the dumping operation can be easily and quickly accomplished without the need of a great deal of manual labor but almost entirely by the pull of the stock.

A further object of the invention is to produce a simple and inexpensive apparatus and yet one which is exceedingly effective for the purposes for which it is designed These objects I accomplish by such structure and relative arrangement of parts as will fully appear by a perusal of the followin specification and claim.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a top plan view of the complete grader. Fig. 2 is a side elevation of the same. Fig. 3 is a side elevation of the same in tilted position.

Referrlng now more particularly to the characters of reference on the drawing the numeral 1 designates the supporting wheels of the grader which are mounted on axles 2 which bend inwardly as shown in Fig. 1 and are bolted to an angle iron as at 3. The angle iron 3 is bolted to transversely disposed angle irons 4c and riveted to the Specification of Letters Patent.

Application filed May 1, 1913.

Serial No. 764,839.

angle irons at are side plates 5 forming the inclosing sides for the grader to hold the dirt confined. The rear ends of the members 5 are slightly curved and fastened to the same by angle irons 6 or other desired means is the grader or scraper 7 the same being provided along its lower edge with a suitable blade 8. The member 7 is suit ably braced to the angle iron 3 by means of a central brace member 9.

The grader is provided with a suitable operating handle 10 which is secured centrally to the member 7 and provided with a pair of side braces 11.

The depth of the cut of the blade 8 is controlled primarily by the handle 10 but its normal position is gaged by means of a shoe 12 secured to a bar 13 pivotally mounted in lugs 14 on the lower edge of the memher 7. At the outer end of the member 13 I then provide a bar 15 pivotally mounted to said member 13 and projecting upwardly and being adj ustably disposed on the handle 10 by means of a bolt 16 adapted to project through said handle 10 and into any one of a plurality of holes 17 in the bar 15 whereby the position of the shoe 12 may be adjusted to hold the blade 8 normally to make a deep or shallow out as may be desired.

Pivotally connected to the sides 5 above and back of the pivotal connection of said sides with the axles 2 are draw bars 18 flexibly connected at their outer ends with a cross bar 19 to which the draft means such as swingle or double trees will be secured. The position of these draw bars may be adjusted by means of bolts 20 adapted to project into any one of a plurality of holes 21 in the sides of the members 5.

Disposed on the front ends of the members 5 are angle irons 22 pointed at their lower ends and adapted to form pivotal points on which to tilt the grader to unload the same, the tilting operation being performed by throwing the handle 10 upwardly and then the pull of the stock on the draw bars 18 continues the tilting operation until the angle iron 3 rests on the bars 18 at which point the grader is in a substantially vertical position which eflfectually empties the load when it can be again tilted to ride on its carrying wheels 1. The members 22 are adjustable vertically by means of bolts 23 adapted to project through the members and into any of a plurality of holes 24 in the said members 22.

The handle has a rope 10 to control it by when the grader is tilted.

The bolts are curved as seen in Fig. 1 and are in turn adjustaloly and turnably disposed to the sides 5 as at 20 to permit of the easy adjustment thereof as will be readily seen.

As can be readily seen from the foregoing description, scraping, leveling and grading of land can be readily and easily ac complished by the use of my improved grader and the depth of cut. and manner of loading and unloading and other handling of the device can be easily controlled by the various adjustments set forth.

lVhile this specification sets forth the preferred form and relative position of the parts of my improved grader, still. in practice such deviations therefrom may be resorted to as will fall within the scope of the appended claim.

Having thus described my invention what I claim as new and useful and desire to sccure by Letters Patentis:

A grader comprising wheels, side plates turnably mounted on said wheels and being supported thereby, a cuttil'lg blade on the rear of said side plates, members secured to the forward ends of said side plat-es and projecting downwardly to points normally a slight distance above the lower plane of said wheels, means permitting said grader to be turned between said wheels to bring said downwardly projecting members into contact with the ground to form pivotal points to throw said grader into inverted position, described.

In testimony whereof I a'li'ix my signature in presence of two witnesses.

CHARLES H. GUNN.
